Check the size of a string

[DigitalExpl0it]

Whats the best way to check a string size before it is inserted into mysql?

I want to limit the ammount of data submitted to the database.

like max 10,000 chrs

If it's user-input data, you could always use the maxlength=xx attribute on the <input> tag in your form.

Or you could Substr( "the_string", 0, length ) the string. This would return length characters from "the_string" starting at position 0 in the string.

I think MySQL just truncates data that is too large for the specified field anyway.

hey thanx for the reply

I was thinking about somthing like this but wanted to know if there is a better way

<?
$var = "this is a test";
$result = strlen($var);
echo $result;
?>

then just see if $result is more than 10000

I reckon, if you only ever wanted $var to be 6 chrs, you could do this:

<?php
  $var = 'blah blah blah';
  $var - Substr( $var, 0, 6 );
  echo $var;
?>

You'd get 'blah b' echoed from that.

But if you only want to know how big the string is, then what you have said would be fine.
